2013 nomenclature test answers

Name __________________
Ionic compounds can be composed of a metal or a positive polyatomic ion to a nonmetal or
negative polyatomic ion.
No prefixes are used when naming ionic compounds.
The metal is named first and its oxidation state needs to be indicated by a roman numeral
if it has more than one oxidation state.
The nonmetal is named second and its ending is changed to ide.
The endings of polyatomic ions are unchanged.
Molecular compounds composed of a nonmetal to another nonmetal can be named using two
naming systems.
Prefixes can be used to indicate the number of each element in the compound. If there is
only one of the 1 st element mono is not used. The ending of the second element is
changed to ide.
The second method is to use roman numerals to indicate the oxidation state of the 1 st
element in the compound while the ending of the second element is changed to ide.
There are three types of acids, each with different naming algorithms.
An acid that contains hydrogen and a nonmetal are named by including Hydro as a prefix
and using an ic as an ending.
An acid that contains hydrogen and a negative ite polyatomic ion is named without using
the prefix hydro and by changing the ending to ous.
An acid that contains hydrogen and a negative ate polyatomic ion is named without the
prefix hydro and by changing the ending to ic.
